Recipe Details
Evidence
"Typical XRF spectra of the writing surfaces of two manuscripts, T-S 8.220, written on paper (in red), and T-S 10J2.2, written on parchment (in green)"
Remarks
Section 3.1 (p. 94) specifically addresses the 'Inorganic Contamination of the Writing Support.' Paper samples showed a wide dispersion of elements like calcium, chlorine, iron, and potassium (Fig 4.15). The composition variation can be used to distinguish between paper produced in different regions or timeframes (p. 98).
